Back in December, we heard that a Chinese company by the name Oukitel was setting out to launch a smartphone with a 10,000mAh battery that could power the device for unto 10 days. The device, named K10000 Pro will start shipping from January 21st.

But that’s not the only device Oukitel is pushing out. Word is that the company also has a smaller K4000 Pro, which, as the name suggests, comes with a 4600mAh battery that promises to give you enough juice for up to 6 days of “normal use” (according to the manufacturer’s standards), and up to 80.5 hours of talk time.

While the main attraction of the device is the massive battery pack, the device also comes with decent specs for a low-priced phone. The K4000 Pro sports a 5-inch, 720p-resolution LCD screen. It is powered by a MediaTek 6735P chipset with a quad-core CPU running at 1GHz. Other features include 2GB of RAM and 16GB of expandable storage memory, which isn’t going to do well under graphic intense games, but that’s also one of the reasons behind the long-lasting battery.

In terms of looks, the K4000 Pro comes with a machined metal frame whose four angles are reinforced to improve its endurance under drops. A 0.4-inch thick tempered glass gives the display device an added protection and durability, so much so that the device substitutes for a hammer, according to the company’s video.

The device will run on Android 5.1 Lollipop and Ouktitel says that it will be upgradable to Android 6.0 Marshmallow later on. The handset supports dual-SIM and comes with basic connectivity features like Wi-Fi, Bluetooth, GPS, and USB OTG.

Oukitel is having a pre-sale event between January 19 to February 1, where it will sell the device for $120. Furthermore, a limited batch of the K4000 Pro will be up for grabs for $90 on Tuesdays.
